Protein rich diet brings about relatively no change in which one of the following constituents of urine?
A. Creatinine
B. Ammonium salt
C. Urea
D. Uric acid

Hint Proteins are made up of building blocks that are known as amino acids. Proteins play an important role for maintaining the growth and repair of the cells, tissues, skin, nails, and hair. There are essentially 20 different types of amino acids that can be combined to make a protein.
Protein rich diet is that diet 20% or more calories comes from protein. Protein rich foods are meat, eggs, legumes, soy, etc.

Complete Answer- Proteins that come from plants are the best because they are less in saturated fat and provide more fibres and are very beneficial for our healthy heart.
Creatinine is a chemical-waste product. It is found naturally in the form of creatine. We take in excess amounts of protein in our diet. The level of creatinine also increases and may lead to various health problems and improper functioning of kidneys.
Ammonium salts are not present in urine so, if we take a protein rich diet the ammonium salts level is not increased.
Urea is a nitrogenous-waste product. When we take an excess amount of protein then the level of urea in urine increases may damage the urothelium and increase the risk of carcinogenesis.
Uric acid is increased when we take protein rich food because the protein contains the high level of purine that leads to the increasing the level of uric acid and this condition known as uricosuric effect.

So, the correct answer is option (B) Ammonium salts.

Note- Proteins are present in every cell of the body without it our life does not exist. High protein diet promotes weight loss also. We need 0.8 g of protein everyday according to our body weight.
If we do not take a proper amount of protein which is required by our body then various health problems increase like reduced immunity, loss of muscle mass, respiratory problems, etc.
